Description

TECHNICAL FIELD The present invention relates to an electronic scale which can be used as a numeric key and also as a product name key when inputting information on an electronic scale.

(Prior Art) A conventional electronic scale exerts a predetermined function by pressing a numeric keypad and various function keys in this order. For example, the "zero" key is pressed in the pre-weighing stage to bring its current output value to "zero" due to the need to adjust the sensor error due to temperature. The "wind setting" key is used to set a known tare weight, and after inputting the weight with the ten keys (for example, if the weight is 5 g, press the ten key 5). Press the “” key to set the tare weight. The “Tare” key is used to set a previously unknown tare weight, and by pressing the tare after placing it on the balance,
The tare weight is set. Further, the "erase" key is used to erase the currently displayed data and perform a new weighing operation. Further, the ten-key pad is used as a numeric key for inputting the tare amount in the wind setting and the unit price in setting the unit price.

On the other hand, the conventional electronic scale is equipped with a large number of product name keys corresponding to the product to be sold in addition to the above numeric keypad and various function keys, and when the key corresponding to the product name of the corresponding product is pressed, it is preset in the storage device. The product price, such as the unit price of the product, was output and input to the computing device of the electronic scale, the display device, the printer, etc. In addition to the numeric keypad and various function keys, If the product name key corresponding to the product is provided, the number of keys will naturally increase, resulting in higher cost and lower reliability.

Further, instead of providing a large number of product name keys, a number is assigned to each product, and a device for reading the above-mentioned unique information by inputting the product number using the ten-key is also used. With the increase in the number of, the number of digits of the assigned number also increased, which often caused a malfunction.

(Problems to be Solved by the Invention) The present invention has been proposed in view of the above-mentioned conventional circumstances, and it is possible to read information such as a unit price using a ten-key pad as a product name key and input the information into an electronic scale. It is an object of the present invention to provide an electronic scale having the function of the above-mentioned device further added with a function of inputting the tare weight into the electronic scale by using the ten keys as numeric keys even in the mode in which unit price information can be read.

(Means for Solving the Problem) An input device of an electronic balance including a numeric keypad and various function keys, a storage device for storing unit price information of a product,
The input mode setting means for setting and operating the following first input means and second input means by pressing the function key, and one of the numeric keys on the numeric keypad after setting the input mode by the input mode setting means First input means for inputting unit price information of the product in the storage device into the electronic scale by pressing as a key, and the function key by pressing the numeric key of the numeric keypad after setting the input mode and then pressing the function key Input the numerical information of the tare weight specified by
The numerical value of the tare weight specified by the input means and the function key is arithmetically processed, and then the price is calculated from the unit price from the first input means and the weight of the object to be weighed from the electronic scale. The electronic scale is the gist of the invention.

(Embodiment) FIG. 1 is a block diagram showing an outline of the case where the present invention is implemented by using a CPU, and FIG. 2 is a flowchart showing an outline of the operation of the CPU. In FIG. 1, the ten-key pad 11 of the keyboard 1 corresponds to any of a large number of products, and has a role of a product name key in the first input means described below, and the second input described below. It can also be used as a numeric key in the means. The storage device 2 stores information such as the unit price and unit weight of each product. Further, a dedicated product name key 11 'is added to the keyboard 1 in addition to the numeric keypad 11, and the product name key 1 is also stored in the storage device 2.
You may make it memorize | store the information of the goods corresponding to 1 '.

As the unique information, the unit price, the unit weight, the tare, etc. may be used individually, or the unit price and the tare or the unit weight and the tare may be used as a set and stored in the storage device 2.

As shown in FIG. 2, the CPU 3 has a setting means 31, a first input means 32, and a second input means 33 incorporated as a program, and controls the keyboard 1 and the storage device 2 as follows.

(I) By pressing any one of the function keys 12 of the keyboard 1, for example, the "winding" key, the setting means 31 is actuated, and the electronic scale by the following first input means 32 and second input means 33 by the ten-key 11 is operated. Can be input to. That is, as described above, in the normal weighing operation, the "winding" key is pressed after the previously known tare weight has been input using the ten-key pad 11, and the operation is the same as the above-mentioned operation in the present invention. There is nothing to press the "wind-up" key. In the present invention, the "winding" key or another function key is used to set and operate the first and second input means 32, 33.

When the first and second input means 32 and 33 are set, desired information can be input to the electronic scale by using the ten-key pad 11.

(Ii) First, the wind key is pressed, and then one of the numeric keys 0 to 9 in the numeric keypad 11 is pressed to activate the first input means 32, and the numeric key of the numeric keypad 11 is used as a product name key. It works, and reads out the unit price or the like that has been input in advance in the storage device 2 as information corresponding to the product name, and inputs it into the electronic scale. The operation of this first input means 32 can be repeated by pressing one of the different numeric keys of the numeric keypad 11, one after another,
Therefore, it is possible to continuously measure a plurality of different products.

(Iii) Numeric keypad 11 pressed in step (ii) above
Keeps its function as a numeric key. That is, separately from the information such as the unit price, by pressing the numeric key of the numeric keypad and then pressing the function key 12, the tare weight specified by the function key 12 is input to the electronic scale as numerical information. In addition to the information such as the unit price, the numeric information of the numeric keys is input to the register 4 of the electronic scale for each key depression, and the numeric information can be obtained by pressing the function key 12 after the numeric keypad operation. The tare weight specified by is input to the electronic scale as information. For example, if 1 and 5 are pressed using the ten-key pad, and then the "winding" key of the function key 12 is pressed, the tare amount of 15 g is input to the electronic scale.

With the above configuration, for example, the unit price or the like, which has a relatively small fluctuation, is previously input to the storage device 2 and the tare weight corresponding to the tare weight is first input means 33. Enter into the electronic scale using
The data can be read from the storage device 2 using the input means 32 and input to the electronic scale. Further, as described above, when the information input to the electronic scale A using the first means 32 and the second means 33 is, for example, a unit price,
It is used when calculating the price by multiplying the weight of the product weighed by the weighing device 5, or when it is the tare weight, the tare weight is subtracted from the total weight to calculate the true weight. It is used as information necessary for the function of the electronic scale, such as used for.

In FIG. 3, the unit price is calculated by the first input means 32 and the unit price is calculated by the second input means 33.
It is a more detailed flowchart about the case of inputting the tare amount.

(I) First, when the "winding" key is pressed as described above (F
11) The input mode setting means operates to set the input mode (F13). By the way, in the normal operation of the electronic scale, the input from the numeric keypad 11 is once entered in the unit price field regardless of the meaning of the numeral, and the function key 12 is pressed after operating the numeric keypad 11 to specify the value with the function key 12. It is given the meaning that is given and used for a predetermined purpose. For example, when performing a wind setting operation, if an input is made using the numeric keypad 11 of a known tare weight, the input is once displayed in the unit price field, and then the "wind setting" key is pressed to input the tare amount. Is processed as. Therefore, according to the present invention, if there is an input in the unit price field before entering the step (i), it is treated as a tare amount,
Since the input mode will not be set, if the "tare" key is pressed, it is judged whether there is a unit price field (F1
2) The input mode is set only when the unit price is zero, and when the unit price is not zero, the air-conditioning operation proceeds as described above.

When the input mode is set in step (i),
In order to confirm that, as shown in FIG.
LED of the "readout" display section 41 provided on the left side of the unit price column of
The lamp is designed to light up.

(Ii) When the input mode is set as above, CP
U3 performs a key check (F21) on the keyboard 1 and only when one of the ten keys 11 is pressed (d in F21), the first input means 32 operates, and the storage device as described above. The unit price reading of the product corresponding to the key from 2 and the input to the electronic scale A are performed. If any key other than the ten key 11 is pressed in the key check (F21) step, another operation is performed. For example, the "winding" key is pressed to set the unit price read mode. When the "zero" key is pressed within a fixed time (F20), a registration mode (F26) for registering the unit price, weight, etc. (only unit price in this example), which is the information used in the present invention, in the storage device 2 ) (F21b). When the "winding" key is pressed (c of F21), the second input means 33 described later is activated.

The steps of reading out the unit price and inputting to the electronic scale can be continuously repeated as described above (F25). For example, when it is desired to weigh three commodities, one of the numeric keys of the numeric keypad 11 corresponding to the first commodity is pressed. Press one to read the unit price (F23), input it to the electronic scale A, put the product on the weighing device 5 and use it for price calculation, and then repeat the same procedure for the second and third products. The unit price of each product can be entered in the electronic scale.

(Iii) The information as the numeral of the numeric keypad 11 pressed in the above step is registered in the register (4) of the electronic scale,
The wind check key is pressed by the setting means 31 and a key check (F2
When the numeric key of the numeric keypad 11 is pressed during the operation of 1) and the "winding" key is pressed, the second input means 33 is activated and the numerical information registered in the register of the electronic scale is used as the tare weight. Input to A. For example, 1 → 5 with ten keys
If you press the and numeric keys in succession, the unit price of the product corresponding to the "1" key will be read in the step (ii) above, and at the same time, the numeric information of 1 will be registered in the register and "5".
The same operation is repeated in the case of the key, and as a result, the numeral 15 is registered in the register 4. At this time, when the "winding" key is pressed, this 15 is input to the electronic scale as a tare weight of 15 g.

However, when performing this wind setting operation, first, the numeric key of the numeric keypad is pressed to set the tare weight, then the "wind setting" key is pressed, and then the numeric key is pressed again to read the unit price.

The input mode set and operated as described above is released by pressing the "erase" key (reset key).
When the "erase" key is pressed, LE of the display unit 41 of the display device 4 is
Turn off D (F24).

Even when the numeric keypad 11 is used as the product name key as described above, if there are 10 or more product types, the product name key will be insufficient, but in this case, the product name key is shown in FIG. Similarly, the product name key 11 'can be added to the keyboard. The means for inputting information such as a unit price to the electronic scale A by using the product name exclusive key 11 'is the first
Input means may be used, or another independent means may be incorporated in the CPU as a program. 6
Is a receipt, 42 in FIG. 3 is for inputting numerical information,
When the wind key is pressed in the key check (c of F21), the tare weight is input to the register of the electronic scale (F27).

Although the numeric keys and the like in the figure correspond to the main program portion, they are omitted in the description of the drawing.

(Effect) As described above, according to the present invention, the numeric keypad can be used as a product name key to input information such as unit price and unit weight in the storage device to the electronic scale by a simple operation, and the numeric keypad can be used as a product name key. Even if it is in the state, it can be used as a numeric key and by pressing the function key next time, the tare weight of the pressed function key can be input to the electronic scale as numerical information, so the numeric keypad It is possible to input the tare weight other than the unit price, unit weight, etc. stored in the storage device into the electronic scale while setting the input mode that can be used as the input mode, so that the operation of the net weight calculation and the price calculation can be simplified. Of.
